Abstract

PURPOSE:To grasp at a glance the whole system or a desired terminal equipment by providing a monitor for displaying in a lump or selectively a state of a terminal equipment, when a power source of a central control device has been turned on, or when a monitor display command has been inputted at any time. CONSTITUTION:When a signal for showing the closure of a power source switch 13 is sent out of a power source turn-on detecting circuit 15, a state recognizing circuit 16 decodes successively output data of state outputting circuits 6-10 and stores it in a memory. Subsequently, the data stored in the memory is led into a character generator and converted to a pattern, stored in a video RAM, and a display is executed. The same control can be executed even in the course of electric conduction, and in response to a monitor display command, the state recognizing circuit 16 and a CRT display 18 are energized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a terminal device management method for a system including a plurality of terminal devices, such as a filing system.

[Prior Art] This type of device has conventionally been equipped with a large number of terminal devices. However, since it was not possible to identify whether each terminal was powered on or not, or whether each terminal was in a usable state, it was not possible for the user to identify all of them at once. After checking each point, start each terminal device (for example, have it read the manuscript),
Alternatively, operations had to be performed for each terminal device to produce output. This was truly inconvenient and inefficient for those using the system.

In particular, when power is turned on to the central control unit, not only this check but also many other determinations are required, which inevitably leads to check errors and the like, resulting in the inconvenience of erroneous operation.

[Objective] In view of the above-mentioned points, an object of the present invention is to check the power-on status of each terminal device connected to the central control unit and its operating status (for example, warming It is an object of the present invention to provide a terminal device management method configured to display the status (whether the device is currently being installed or not), thereby making it possible to grasp the status of the entire system at a glance.

In order to achieve this object, the present invention is characterized in that a system including a plurality of terminal devices is provided with a monitor means for displaying the operating states of the terminal devices collectively or selectively.

Hereinafter, the present invention will be described in detail with reference to the drawings.

[Embodiment] FIG. 1 shows an embodiment of a filing system to which the present invention is applied, and shows how a large number of terminal devices are connected. In this figure, l and 2 indicate a first league and a second reader, respectively, which read documents when filing is executed.

Reference numerals 3 and 4 denote a first printer and a second printer, respectively, which are used to print out already filed information again.

Reference numeral 5 denotes an optical disk, which stores information read by the first reader 1 or the second reader 2.

Reference numerals 6 to 10 each indicate a status output circuit, which notifies the central control unit 12, which will be described later, of the operating status of each terminal device. In these status output circuits 6 to 1O, when the power of each terminal device is not turned on, the output terminal thereof is in a high impedance state S (that is, a disconnected state S).
When each terminal device is powered on, it not only sends out a status signal indicating that the power is on, but also indicates the current operating status (for example, whether it is warming up or printing). Send out the signal to display.

Reference numeral 11 denotes a signal path (bus) that guides the above-mentioned signals sent from the status output circuits 8 to 10 of each terminal device to the status recognition circuit 16.
It is.

Here, the state recognition circuit 1B decodes and recognizes the signals sent from the state output circuits 6 to 10.

The central control unit 12 that centrally controls the entire system further includes a power switch 13. Power supply circuit 14. A power-on detection circuit 15 for detecting power-on of the central control unit and a CRT display output circuit 17 are provided. This CRT display output circuit 17 is an output circuit for displaying data obtained from the state recognition circuit 1G on the CRT display 18.

The operation of this embodiment is as follows.

First, by closing the power switch 13, the central controller 12
When the power is turned on, the power-on detection circuit 15 detects the power-on.

Then, the status recognition circuit 16 decodes the signals from the status output circuits 6 to 10, and the operating status of each terminal device 1 to 5 is determined from the CRT.
The image is displayed on the CRT display 18 via the display output circuit 17.

FIG. 2 shows an example of a display on the CRT display 18.

According to this example, the first league is OFF and the second league is R.
EA[]Y (i.e. readable state 1), 1st
It can be seen that the printer is WARNING UP, the second printer is OFF, and the optical disc is WARNING UP.

FIG. 3 is a flowchart showing the control procedure to be executed by the state recognition circuit 16 and the CRT display output circuit 17.

First, when a signal indicating the closing of the power switch 13 is sent from the power-on detection circuit 15 (step S1), the state recognition circuit 1B sequentially decodes the output data of the state output circuits 8 to 1O and stores them in the memories Ml-1lI5. (not shown) (steps 82 to S8).

Thereafter, the data stored in memory 5 is introduced into a character generator (not shown) to form a pattern, which is then stored in a video RAM (not shown) (Step S6) and displayed. The contents of this display are as already described with respect to FIG.

In the above-described embodiment, the operation at the time of power-on has been described, but it is also possible to perform similar control while the power is being supplied. That is, in response to the monitor display command, the state recognition circuit 1B, the CRT display output circuit 17. ,
, the CRT display 18 may be energized. It is also possible to configure such a monitor display command to be sent only when the password is keyed in using a console key (not shown).

In addition, in this embodiment, the explanation has been made on the assumption that each terminal device is independently equipped with a power switch (not shown), but the central control device 12
It is also possible to collectively control the turning on of these power sources.

[Effects] As explained above, according to the present invention, the status of the terminal devices can be displayed all at once or selectively when the power is turned on to the central control device or when a monitor display command is input at any time. - It becomes possible to grasp the entire system or desired terminal equipment at a glance. As a result, erroneous operations due to check mistakes and the like are prevented, and efficient and accurate operations are possible.
